#Fiber connector types spf Patch#
Simplex fiber patch cable is consist of single fiber core, while duplex fiber patch cable is consist of two fiber cores and can be either singlemode or multimode. In addition, there is 10G OM3 and OM4 multimode patch cables which cable jacket are usually aqua. Single-mode patch cables are with 9/125 fiber glass and are yellow jacket color, while multimode patch cables are with OM1 62.5/125 or OM2 50/125 fiber glass and are orange color. The word mode means the transmitting mode of the fiber optic light in the fiber optic cable core. Fiber optic patch cables are used in two major application areas: computer work station to outlet and patch panels or optical cross connect distribution center. According to fiber cable mode, cable structure or connector types etc., fiber patch cable can be divided into different types.ġ.Single-mode and Multimode SFP fiber CableĪccording cable mode, patch cables can be divided into single-mode and multimode fiber patch cable. It is composed of a fiber optic cable terminated with different connectors on the ends. There are many optical transceivers types, such as SFP+ transceiver, X2 transceiver, XENPAK transceiver, XFP transceiver, SFP (Mini GBIC) transceiver, GBIC transceiver and so on.įiber optic patch cable, also known as fiber jumper or fiber optic patch cord.
Usually, it is inserted in devices such as switches, routers or network interface cards which provide one or more transceiver module slot. Before starting this topic, it is necessary for us to review the basic knowledge of the fiber optic transceiver and fiber optic cable.įiber Optic Transceiver is a self-contained component that can both transmit and receive. But with so many different kinds of SFP fiber cables available in the market, which one is suitable for may optical transceiers? This article may on this issue to provide some solutions. Other long haul transmission standards include 1000BASE-LX10, 1000BASE-EX and 1000BASE-ZX.SFP fiber cable and fiber optic transceiver have become more and more important in fiber optic data transmission, especially in data transmission between the switches and equipment. Among them, the 1000BASE-LX is a standard, the other two just are terms widely used by vendors. In a word, these three modules are all referred to Gigabit Ethernet transmission. Unlike that, 1000BASE-LH SFP operates a distance up to 70 km over single mode fiber. 1000BASE-LX/LH SFP can achieve a distance up to 20 km over single mode fiber. Many vendors use both of them for certain SFP modules, but they aren’t a Gigabit Ethernet standard at all.
#Fiber connector types spf install#
For link distances greater than 300 m, you must install a mode-conditioning patch cord between the transceiver and the MMF cable on both ends of the link.ġ000BASE-LH and 1000BASE-LX/LH Optical Interface Specifications The 1000BASE-LX SFP is specified to work over a distance of up to 10 km over single mode fiber and it can also run over all common types of multimode fiber with a maximum segment length of 550 m. Gigabit Ethernet 1000BASE-LX Optical Interface Specificationsġ000BASE-LX is a fiber optic Gigabit Ethernet standard specified in IEEE 802.3 Clause 38 which uses a long wavelength laser (1,270–1,355nm). 802.3z is commonly referred to as 1000BASE-X, which is used in industry to refer to Gigabit Ethernet transmission over fiber, where options include 1000BASE-SX, 1000BASE-LX, 1000BASE-LX10, 1000BASE-BX10 or the non-standard -EX and -ZX implementation. The initial standard for Gigabit Ethernet was produced by the IEEE in June 1998 as IEEE 802.3z, and required optical fiber. Gigabit Ethernet was the next iteration, increasing the speed to 1000 Mbit/s. Ethernet later evolved into a widely implemented physical and link layer protocol. Fast Ethernet increased speed from 10 to 100 megabits per second (Mbit/s).
The Commonly Used 1000BASE-X Standards about EthernetĮthernet was the result of the research done at Xerox PARC in the early 1970s. Whether they are the same or different? If they are dissimilar, what differences between them on earth?
We usually see LX SFP, LH SFP and LX/LH SFP on many websites, and many people show their confusion about them.
